Q: Apple Extreme Time Capsule Networking
Hello. I am trying to set-up a wired / wireless network using (2) AirPort Extreme Time Capsules and (2) AirPort Extremes.
My "base" AirPort Extreme Time Capsule is connected via Ethernet to my Comcast cable modem as the primary Internet feed. I have an iMac connected via Ethernet to the AirPort Extreme Time Capsule.
To gain Internet connectivity to other parts of our house, I have a LinkSys Powerline connected via Ethernet to my "base" AirPort Extreme Time Capsule (in back office of house). I have a second Linksys Powerline connected to another AirPort Extreme (in front of house). My hope was to simply connect iPads / iPhones to this AirPort Extreme...there are no Ethernet connected computers.
I have a 2nd AirPort Extreme Time Capsule also connected to a LinkSys Powerline via Ethernet. I have a MacBook Pro connected via Ethernet to the 2nd AirPort Extreme. Further, my Internet connection is incredibly slow or non-functioning.
I am getting an error on both iMac and MacBook Pro that "The Hostname is already in use on this Network." I have tried to EDIT the "Computer Name" in SHARING folder.
When I disconnect all PowerLine and AirPort Extreme (2) and AirPort Extreme Time Capsule (1), and only have the "base" station AirPort Extreme Time Capsule active, my Internet connectivity is ample.
Clearly, I am missing something in the configuration of that seems to me to be a pretty straightforward set-up? Could it be a PowerLine compatibility issue? Could it be a Comcast issue? Thoughts?
